What are the Recent Developments in Global Kallmann Syndrome Market?

• In April 2025, a study reported two male patients with KS caused by a novel mutation in the ANOS1 gene (c.90_100dupTGCTGCGCGGC, p.Arg34Leufs*25). The cases presented with delayed puberty, penile hypoplasia, olfactory dysfunction and low LH/FSH/androgen levels, with imaging showing small pituitary volumes and thin stalks. The novel mutation expands the known pathogenic spectrum of ANOS1
• In April 2025, another report described a boy with KS due to a balanced X-chromosomal pericentric inversion disrupting the ANOS1 gene. This cytogenetic finding is rare: rather than a simple point mutation, a structural chromosomal rearrangement caused KS. The breakpoints were mapped to intron 3 of ANOS1 and an intergenic region at Xq21.1, suggesting replication-based error mechanisms
• In April 2024, a single‐patient case study from China described a KS patient carrying both an IL17RD variant (c.2101G>A, p.Gly701Ser) inherited from the mother and a novel CPEB4 variant (c.1414C>T, p.Arg472*). The research provided detailed phenotype data: olfactory nerve deficits on MRI, slightly small pituitary gland, hormone deficiencies and whole-exome sequencing confirmation of the two variants
• In May 2023, a clinical case in Italy reported a male patient with KS carrying a novel variant in the KAL1/ANOS1 gene (p.R46H: c.137G>A) along with a CHD7 gene variant (p.L2806V). The patient had hypogonadotropic hypogonadism and anosmia, imaging showed absence of olfactory bulbs, and genetic analysis revealed two previously undescribed variants
• In June 2022, the study “Advances in Genetic Diagnosis of Kallmann Syndrome and Congenital Hypogonadotropic Hypogonadism” detailed how next-generation sequencing (NGS) and oligogenic inheritance models are shifting the diagnostic paradigm for KS. The review outlined that KS is highly heterogeneous both genetically and phenotypically, with ~40 % of cases having identifiable defects
